Development of the Preceptor Self-Assessment Tool and Use of the Content Validity Index

Background Competency of staff nurse preceptors is an essential factor that determines the success of preceptorship experiences. Competency assessment is complex, and no self-assessment tool exists. Method This article describes phase two of the development of the Preceptor Self-Assessment Tool (PSAT). A content validity index (CVI) survey was completed by 11 subject matter experts to determine relevance of items on the PSAT. Results The Scale-Level CVI (S-CVI) for the instrument was 0.91, and the items CVI ranged from 0.45 to 1.0; most were above 0.78. One item was dropped and three were collapsed, leaving the final number of items at 64. Conclusion The items on the PSAT have undergone content validity and have been found to be highly relevant. Pilot testing in a large sample of preceptors is warranted to further refine the items on the tool. [J Contin Educ Nurs. 2020;51(10):469-476.].
